[BlueZ,2/3] client/player: Expose transport "select" method to the user

Commit Message

Vlad Pruteanu July 10, 2024, 8:13 a.m. UTC

This exposes the "select" method for Broadcast transports. This
allows the user to select the desired stream when running the setup
with PipeWire since it acquires any transport that is pending.
